  • This has the consequence that the friction acting on the Spulgut 2 between stop member 40 and end face 39 increases, which in turn has the consequence that increases the tension of the Spulguts 2 between the end face 39 and stop member 40 and the traversing 5.
  • This increased tension has the consequence that the winding material 2 is pulled with a greater force against the cutting edge of the cutting device 26, whereby the severing is then caused.
  • the funnel-shaped extension of the housing 27 forms an insertion region 42 for the winding material suction gun.
  • a winder 1 is shown with only one winding station 43, where quite in a winder 1 and several winding stations can be operated in parallel.
  • the holding device 11 according to the invention is used as an initial equipment for the winder 1 with their delivery to the customer.
  • the holding device 11 according to the invention is marketed as a retrofit product for already previously distributed winding machines 1 and is used.
  • a control device that a severing of the Spulguts 2 is carried out, which with a time delay or a deceleration of Spool 7 and / or unlocking the sleeve 8 can be triggered by the spindle 9.
  • additional can be evaluated, an output signal of the sensor 31, by means of which it is detected how far the suction nozzle 37 of the winding material suction gun 44 is inserted into the receptacle 19.
  • a holding device 45 can provide both the holding device 11 and the last of these upstream deflection means 3 as a compact structural unit.
  • slot and "exit slot” any embodiment with rectilinear or curved longitudinal axis and the same or varying slot width is included.
